>If anyone happens to have one of these out of the case, would they please send me a picture of the area around the 3Q5 25Z6 tubes.  I am restoring mine (finally) and there are some wires cut off.  Also, what are the values of the 2 largish resistors on the 3Q5.  The schematic shows 330 Ohms for R29, and 27 for R30.  Mine measure 990 Ohms and 45 respectivly.  I suspect they have changed value in the last 66 years.

Can't help you with the wires, but it is certainly common for carbon composition
resistors to change value that much with time.  So I'd replace with what the schematic
calls for.
